Fuel tank overflow hoseBefore operating the vehicle:
Check the fuel tank overflow hose
connection.
Check the fuel tank overflow hose
for cracks or damage, and replace
it if necessary.
Make sure that the end of the fuel
tank overflow hose is not blocked,
and clean it if necessary.
Make sure that the end of the fuel
tank overflow hos e is positioned as
shown.

Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10863
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:
Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up ofheat.

Adjusting th e shock absorber
assembly
WARNING
EWA10222
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.
Do not tamper with or attempt to
open the cylinder assembly.
Do not subject the shock ab-
sorber assembly to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.
Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.
Do not dispose of a damaged or
worn-out shock absorber as-
sembly yourself. Take the shock
absorber assembly to a Yamahadealer for any service.
NOTICE
ECA10102
To avoid damaging the mechanism,
do not attempt to turn beyond themaximum or minimum settings.
For YZF-R1:
This model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, fast compres-
sion damping force, and slow
compression damping force can be ad-
justed.
Spring preload
1. Loosen the locknut.
2. To increase the spring preload and thereby harden the suspension,
turn the adjusting ring in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting ring in
direction (b).
The spring preload setting is deter-
mined by measuring distance A.
The longer distance A is, the high-
er the spring preload; the shorter
distance A is, the lower the spring preload.
Use the special wrench includ-
ed in the owner’s tool kit to
make the adjustment.

TIP
Although the total number of clicks
of a damping force adjusting
mechanism may not exactly match the above specifications due to
small differences in production, the
actual number of clicks always
represents the entire adjusting
range. To obtain a precise adjust-
ment, check the number of clicks
and modify the minimum and stan-
dard specifications as necessary.
When turning the damping force
adjusting bolt in direction (a), the 0
click position and the 1 click posi-tion may be the same.
For YZF-R1M:
This model is is equipped with ÖHLINS
electronic racing suspension.
Compression damping force and
rebound damping force
The compression and rebound damp-
ing forces are electronically controlled
and can be adjusted from the MENU
screen. See ERS on page 4-19 for in-
formation on how to adjust these set-
tings.
Spring preload
The spring preload adjustment is per- formed manually.

CanisterThis model is equipped with a canister
to prevent the discharging of fuel vapor
into the atmosphere. Before operating
this vehicle, make sure to check the fol-
lowing:
Check each hose connection.
Check each hose and canister for
cracks or damage. Replace if dam-
aged.
Make sure that the canister breath-
er is not blocked, and if necessary,
clean it.

Engine oil and oil filter
cartridgeThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level 1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Wait a few minutes until the oil set- tles, and then check the oil level
through the check window located
at the bottom-left side of the crank-
case.TIPThe engine oil should be between theminimum and maximum level marks. 4. If the engine oil is at or below the
minimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.
TIPCheck the oil filler cap O-ring for dam-age, and replace it if necessary.
To change the engine oil (with or
without oil filter cartridge replace-
ment)1. Remove cowling A and panel B. (See page 7-8.)
